Whenever the city or any officer thereof has reason to believe or has been notified by the state Department of Public Health that there is danger that rabies exists and may spread within its jurisdiction, it shall publish a notice in the official newspaper or newspapers of the city that all persons within its jurisdiction owning or having charge of any dog be required to confine such dog. Other animals may be included in the order whenever, in the opinion of the officials of the city, this is thought to be necessary. (Prior code § 10-3-23)
